s claims. (clins-i135) My `present invention, broadly considered, has todo with improvements in portable, knock-down `seats of the type designedto be folded up in a compact parcel and stored, or transported fromplace toplace, and then quickly setup for use I when and whereneeded. Tothat end, I have 'provided a seating device, wherein but one supeporting leg is used, `and wherein a leverage arf rangement effected by ahorizontal bar and a knee engaging member properly throws the weight ofa person on the seat and supporting leg and maintains the balancerequired for comfortable and relaxed seating.

` In carrying out the above objects of my invention, I employ ahorizontal bar on `one end of which is adjustably mounted, and spaced`upwardly therefrom a transverse member which engages over the knees,andat the opposite end of the bar is provided a seat, and below the seata supporting leg. All of the above parts are movable or foldable into acompact parcel. The load represented by a person occupying the 'seatnecessarily requires at least a three-point support support forstability and to that end, the

horizontal bar and transverse bar engaging over the knees `comfortablyand conveniently distributes the` stresses so that an equilibrium ismaintained and a person is properly seated and relaxed.

Other and equally important objects and advantages oI.' my inventionare; (1) to provide a seat having a minimum number of parts, there beingbut one supporting leg, and those parts arranged to comfortably supportthe load; (2) to provide f means` for folding or moving the parts toform a parent from the following detailed description ing in dottedlines the manner of `folding'the same;

In the drawings wherein like characters vof reference are used todesignate like or similar parts: p

The numeral I designates a leg or supporting post, which has a rubberfoot 2 to prevent scratching of surfaces on which the seat is used.Hingedly connected as at 3 to the Itop of the leg is a horizontal bar 4.It will be noted that one leaf of the hinge engages one side of the legand that the other leaf engages the under side of the horizontal bar ata point spaced from its end, so that the overhanging portion 5 of thebar 4 engages in set-up position on the end of the leg I and overliesthe opposite side of the leg. Bolted as at 6 to the overhanging part ofthe horizontal member 4 is a seat member 1 properly curved and formed t0t the body. vThe seat has xed engagement with the squared end 8 of Ithebolt 6 and the bolt is pivotally mounted in the bar 4 and has, a wingnut 9 on its threaded end. An angle iron I0 is attached by the hingebolts II to the top of the leg I and its outstanding arm is slotted asat I2 to receive the bolt 6 so that the bolt 6 functions to hold the legin vertical position of the bar 4 when the wingl nut is screwed down asin Figure 8, or upon release of the nut the bar may be swung down to lieagainst the leg I as in the dotted line position of Figure l. The seat 1lies transversely of the bar 4 in active position and parallel with thebar 4, as in Figures 4 and 5, in passive or folded position.

The opposite end of horizontal bar 4` is provided with a plurality ofspaced, aligned openings I3 through a selected one of which extends abolt I4. The bolt extends upwardly a predetermined distance and carriesa spacing member or sleeve I5. At the top of the bolt is mounted a kneebar I6 which is suitably shaped to fit over the knees and which may beswung to an inactive position-as in Figures 4 and -parallel with bar 4.A reinforcing rod I1 is provided in the end of the bar. The knee bar isplaced over the knees and adjusted in openings I3 to fit the size of theperson occupying the seat 1, and the entire device may be folded into acompact parcel when f i* i if fa, i

It is it'eltvesiftl, af the Opettonzallldfadtantages of my inventionwill be apparent from the foregoing, but it is emphasized thatinterpretation of the scope thereof should only be conclusive when madein the light of the subj'ind claims.

I claim: 1. A seat comprising a horizontal han. asingle Cil :the910120511@ end of thevhrzoptalber, a Spacing element on the bolt betweenthe knee bar and the horizontal bar, and means for adjusting theposition of the bolt on the horizontal bar to adsupporting leg attachedto one end of Athe h orizontal bar, a seat attached to said end 'of'the" :horizontal bar, anda transversely extending knee engaging barattached intermediate its ends to the opposite end of thlelhofizonta'lbaranda spacing element between the horizontal bar and the knee engagingbar. Y n

' A seat comprising a 'orizontal bar, ,a .single supporting leg hingedlyattached. to one end of the horizontal bar,'a seat piv'otally attachedto said end of the horizontal bar, andra transversely extending 1knee'engaging' bar -pivotally attached justthe distance between the knee barand the seat.y

`4.`The invention as dened in claim 3, and

meansrfor holding the leg in a position at right anglesto the horizontalbar.

5. The invention as dened in claim 3, and an .anglefiron carried by thevend of the, leg, `adjacent the horizontal bar, and means, forattach-ingithe same to the horizontal b arfto hold the ylegsubstantially .at right angles thereto, said .means being releasable. y

6. The invention defined in claim 3 wherein the horizontal bar ,hasplural, spacedlaligned .openings in a selected one of which the knee barbolt is receivable. i FRANK A. KUNTZ.
